Travel & Transport on Aegina

Good travel links to Aegina from Piraeus, especially between Hydra and Aegina so I can spend time with my family and friends on the 'other' island, is very important. So here I will add getting to Aegina: its ports, passenger & car ferries, and hydrofoils.  Getting around Aegina, cars, and the cost and ease of filling up, quads, bikes, and cycle hire. Taxis, horse and buggy, buses, boat hire. Links to other islands and mainland.
